The correct answer is B) End-for-ended. According to the regulations for lifeboat falls, lifeboat falls must be end-for-ended at 30-month intervals. This means that the falls must be reversed, with the end of the rope that was previously attached to the boat now being attached to the winch or davit. This helps to ensure even wear on the entire length of the fall and extends the useful life of the rope. The other options are incorrect because: A) Renewed does not accurately describe the required action, C) Weight tested is not done at 30-month intervals, and D) Inspected, while important, is not the specific action required by the regulations at the 30-month interval.
